LAYOUT XL - auto route - route with wire assistant overrides

anandmohan

Hi ,

Scenario : I am using cadence version IC6177 , layout xl and exploring auto route option for routing between analog modules. On right clicking the net , choosing the option .. net ->route with wire assistant overrrides , the routing of that particular net is done. But the issues is , the routing is done over the modules and not in the free space though the module has blockage and dummy exclude layers.

Is there any way to avoid the routing over the modules?

I tried to set the environmental variable - setTreatBlockageAsMetalLayers with the following command

envSetVal("layoutXL"  "setTreatBlockageAsMetalLayers" 'boolean t)

And  error occurs , saying this value cant be set.

Please suggest some ways to execute.

Thanks,

Anand
